Correct Answer

A. \(\sqrt{121}\), (11) पर\(\sqrt{121}\), at (11)

Step 1

Concept

The new hypotenuse is \(\sqrt{120+1}=\sqrt{121}\), and \(\sqrt{121}=11\). When a perfect square appears, write its exact value.

Step 2

Why this answer is correct

The correct answer is A. \(\sqrt{121}\), (11) पर / \(\sqrt{121}\), at (11). The new hypotenuse is \(\sqrt{120+1}=\sqrt{121}\), and \(\sqrt{121}=11\). When a perfect square appears, write its exact value.

Step 3

Exam Tip

नया कर्ण \(\sqrt{120+1}=\sqrt{121}\) होगा और \(\sqrt{121}=11\) है। पूर्ण वर्ग दिखे तो उसका सटीक मान लिखें।
